Please What

What is your reason for calling these gilled mushrooms boletes? Boletes are generally pored, not gilled. There are rare exceptions, but why assume a rare exception when you don't know? There may be some confusion underlying your question.

I'd say that's Pleurotus ostreatus, the common oyster mushroom. Could be P. pulmonarius but the top looks a bit dark. Texture and colour seem right for P. ostreatus.

I see no reason to doubt this is Pleurotus, probably ostreatus. I'm not the most knowledgeable but you have one vote in favor of this ID.

There is a fungus called "gilled polypore", Trametes betulina Might not be it but it's a suggestion for where to look. Good luck

Edible Hygrophorus & Hygrocybe spp. Russula xerampelina group spp. Maitake, although rare in Sweden

Wow. It seems to have ridges like a chanterelle, but huge and with a scaly cap. I have no ID suggestion but am very intrigued by this find!

Are they gilled mushrooms? Or polypores? First thought, chicken of the woods. Second thought, some kind of oyster mushrooms. Mature specimens in either case. Anyway the picture isn't clear enough for me to be certain of anything at all! It could perhaps be many other things. Maybe someone more knowledgable will be able to pin it down just from this picture.

Marasmius oreades is a good find. Tasty and strong but neutral flavor. The mushrooms in your pictures look old and are hard to ID. If i had to guess, i'd say they're not Marasmius oreades. If they are, they're likely past their prime. Like Dave says, this clustered manner of growth isn't typical for the species.

It looks a lot more like a blewit. Maybe spore print is best to feel sure. They're not really very tasty imo. To me they're mostly an exciting find because they look cool and are theoretically edible...

To me it clearly is capnoides. Sulphur tufts always have a pronounced yellow-green. Perhaps i've missed something, but to me the confusion seems overstated. However, i too haven't gotten around to trying capnoides beyond a nibble for ID. Seemed like a good edible, but not as special as many others. Skipping them might be for the best if you feel uncertain in the least.

It could be the aptly named "birch polypore", Fomitopsis betulina.

I would say yes. However, i don't have much experience identifying these. Dark edge on cap, slightly wavy stalk and overall size point in the right direction. If the stalk is a bit tough and flexible, that's even better. No toxic lookalikes AFAIK.

Could be a Hypholoma. My first thought is Hypholoma capnoides. Bottom part of stalk would be helpful. Usually Hypholoma is found on dead trees. Maybe you've got some dead tree stuff under your lawn?

The pointing in pic 3 is really on point.

Oysters are always a nice find, and among the most delicious. Chanterelles are the most exciting to stumble upon, because i find it hard to understand their habitat. Hedgehogs (H. repandum) are as good as chanterelles but almost too easy to find around here. Chicken of the woods can be fun to harvest, in a special way. Last time me and my S.O had to duct tape some sticks together into a 14 feet pole in order to poke it down in small pieces. The lazy part of me has a special liking for mushrooms growing in lawns, such as Agaricus spp, some Suillus spp, Marasmius oreades and parasols. Sparassis crispa was a rush to find the one time i stumbled upon a few good enough specimens. And also of course Boletus edulis, because it's so big and tasty. And also Lactarius deterrimus and L. deliciosus. Ok, so basically all of them... Craterellus tubaeformis is probably the only one i don't particularly enjoy harvesting. It's too easy and they're so many. It quickly becomes a chore.
